BOX-COVERING MACl-HNE.

. SPECIFICATION forming part of Letters Patent No. 706,515, dated. September 9, 1902. Application filed June 27, 1898- Serial No. 684,541. (No model.) I

To all whom it may concern;

Be it known that I, CHARLES E. BALDWIN, a citizen of the United States, and a resident of the borough of Brooklyn, city of New York, State of New York, have invented certain new and useful Improvements in Box- Covering Machines, of which the following description, taken in connection with the drawings herewithaccompanying, is a specification.

This invention relates to that class of machines adapted for applying an external covering of paper or other suitable material upon a box and which usually embody a revolving form or box-holder, a reel carrying a strip of paper or box-covering material, and meansior rendering the covering-strip adhesive;'whereby it will be caused to adhere to the box when is turned by the revolving form on which it is held. In addition, however, to thus covering the external sides of the box as accomplished by the machine it is desirable that the coveringstrip should also be turned ovenand around the edges of the box to give the latter To accomplish this, it has heretofore been the practice to have the covering-strip of greater width than the box,whereby i t wi ll loosely project at either side beyond the edge of the box after being applied thereto upon the machine. After the covering-strip has thus been apfrom the form or holder and the loose projectof the box and pressed against the bo'ttdm and inner sides of the same by hand. This hand method of locating'the striparound the edges one;"and it has beenthe object of my present invention to provide a machine by which the complete operationot' locating the coveringstrip upon the box, as'above referredto ql. e.

box and turning one loose projecting edge around the upper edge ofthe box and against the inner side of the same and the other loose edge around the lower edge of the box and against the under side of the same-may be automatically performed. This object I se cure by means of the construction, arrangeafter set forth the claims.

smoothing and pressing the covering-strip against the several external sides of the box,

in detail, and pointed out in and means for turning or bending the loose p rojecting edges of the strip around the adjacent edges of the box and pressing one of the same against the bottom of the box and the other against the inner wall of the box.

Referring to the drawings, Figure l isa front elevation of a machine embodying one practical form of my invention. Fig. 2 is a plan view of the same. Fig. 3 ,is a'vertical section taken through line 3 3 of Fig. 2. Fig.

20 is a cross-section taken of Fig. 3. r

In the drawings, a represents the main supporting-frame, which is suitably constructed to sustain the several operative parts of the machine. Attached to one side of this frame through line 20 2O pleted their action upon the,

isa plate or head (1, having a vertically-arranged groove in one side thereof,in' which two blocks a a are'seated, with a space between the same and each being provided with a groove'in their opposite faces. A plate I) is supported with one side thereof extending IOO between the said blocks a a and provided with ribs 1) thereon, which fit. in the facegrooves of said blocks, as more clearly shown in Figs. 1 and 20,whereby the plate will be re-. tained in connection therewith and be guided when operated, as will 'hereinafter be described.

On the forward edge of the plate I), which is also provided with lateral ribs 12 ablock b is supported to be vertically movable by having a groove therein to receive said ribs on the plate, whereby a dovetail connection is secured between the parts. This block b is held in an adjustable vertically-stationary position relative to the plate I) by means of an adjusting-screw b, which is supported by the overhanging end of a fixed plate 12 on the top of the plate b,by which it-is heldfrom endwise'movement, and 'at its lower threaded end engages with the block b within a screwthreaded opening therein. Supported within ahorizontally-arranged bearing in the block b is a hollow shaft c,which carries at one end thereof the box form and holder. This boxform, as herein illustrated and more clearly shown in Figs. 9, 10,and l1,consists of a headpiece c, having a screwthreaded opening therein to receive the end of the shaft 0, on which latter it is detachably held in a fixed position'by a nut Located upon this headpiece are two longitudinally-movable sliding platese 0 each of-which is provided with two blocks 0 o having a sliding dovetailed connection therewith. These blocks 0 a are each provided with a fixed horizontallyextending arm 0 arranged parallel with each other, apon'the o'uter ends of which a box is adapted to be placed and supported. The several arm-carrying blocks 0 and their supporting-plates c are adjustable for the.

purpose of' allowing the box-holding arms to be changed in position relatively to each other, whereby the same may be adapted for holding boxes of different forms and sizes. As a simple and desirable means of adj usting such parts a screw 0 is centrally connected witha fixed part of the head 0' to be end'wiee stationary andat its opposite threaded ends engageswith the plates 0 0 whereby as the screw is turned, its opposite ends being provided with right and left hand I threads,respectively,the opposite plates, with their supported-blocks, are moved either to ward or away from each other. Adjustment of the said blocks is secured in the opposite direction by means of two screws 07 c ,which are centrally connected with a fixed part of the plates 0 c to be endwise stationary and engage at their opposite ends, which are provided with right and left hand threads, respectively, with the sliding blocked a to move the same longitudinally on the plate 0 The box-covering strip e, as herein shown, is carried by a reel, 6, which is journaled on a bret-arm-e ,attaehed to thefram'e a, and sgn'ided. from the reel'over a moistening or pasting roll .e and from thence to a position adjacent to the box over a series of inported by a part of the frame a. The boxcovering strip may for certain features of my invention be applied to the several sides of the box by hand; but it is desirable that the same should be automatically located and pressed thereon. To provide for this, a carriage d, having a rotary brush d journaled thereon, is supported to have a horizontal sliding movement in the upper part ofthe frame a by having longitudinal ribs cl d on its opposite sides seated within horizontally-arranged grooves or guideways d d in the opposite inner walls of the upper part of the frame a, as more clearly shown in Fig. 3.

In applying the covering-strip to the box the free end of the same is pressed by the operator on that corner of the box farthest from the reel, as shown in Fig. 1, and the carriage d is then operated to move horizontally beneath the box, whereby the brush (1,

both smooth and press the pasted-coveringstrip against such side of the box. The carriage d, with its supported brush, may be opsuited to thus reciprocate horizontally be neath the box-form by any suitable ,means, the means as herein shown being as follows: The shaft d upon which the brush is secured, is journaled in bearings formed in the side walls of the carriage, with its ends projecting laterally beyond said walls. Alever d pivotally supported at its lower end upon a shaft (1 attached to the supporting-frame, is connected at its upper end with one end of the said brush-carrying shaft 01 through the medium of a link (1 and isprovided with a fixed arm or extension (2 which connects with the opposite end of the shaft d also through the medium of a pivoted link d"', as clearly shown in Fig. 3. As a means for vibrating the lever d to move the connected carriage back and forth in proper time relative to the movements of the box-holder, as will hereinafter be referred to, I have connected said lever through the medium of a pitman f with a driven from the main driving-shaft h through the medium of an intermediate shaft 9 by means of a small gear h onthe driving-shaft meshing with a gear g on the shaft g and a segmental gear 'g on the latter meshing with a gear f on the said crank-shaft f, as shown in Figs. 1 and 12. The shaft f being thus operated directly from the segmental gear 9 it receives an intermittent movement which is communicated to the carriage d. The brush (2' isadapted to be rotated as it is moved beneath the box in order to better insure the spreading and pressing of the covering-strip se'cu ringsuch rotation I have located a pulley illpon one end of the brush-carrying shaft (1, two pulleys t" 41 upon the pivot-pin which concran'k f on a rotating shaft f, which latter is.

against 'the lattein, As a simple means fornects the lever d and link d two pulleys 1' 2 termediately-arranged cross-arms e supcarried thereby, may be caused to rotate and r roasts upon the shaft dfi which carries the lever d and a pulley i upon'the driving-shaft h, the

several pulleys being operatively connected by belts 2' tiand 21 whereby the brush is,

driven from the main driving-shaft during the forward and backward movements of the carriage 01. After the brush has been carried forward beneath the box and to a position beyond the end of the same the box is then slightly elevated to be above the path of the brush during its, backward or return movement. When the brush has returned to its starting position, it is rendered temporarily stationary prior to its next forward movement by reason of the segmental gear g moving from engagement with the gear in order tofiallow the box to'be partially turned to present another side in aline parallel with thepat-h of the brush. Such raising and turning of the box may be secured by anysuitable means, the means as herein shown being as follows: The said vertically-movable plate I), by which the box-holder is carried, as hereinbefore described, is provided with an antiiriction-roll b? at its lower end, which rests upon a cam j, as more clearly shown in Figs. 1 and 13.

This cam i's'secured upon a shaft j, which is operated from the rotating shaft-g by means of a segmental gearj thereon meshing with a gear on the said shaft j.

Inthe operation of the machine immediately after the brush has moved forward beneath the box, as described, the three-toothed portion of the gear 7' meshes with the gear j and causes a slight rotation of the shaft j with its cam j. This movement of the cam elevates the plate I) sufiiciently to move the connected box-holder above the path of the brush during the return movement of the latter. After the' cam j has thus been operated to raise the box-holder it remains stationary to holdthe latter in such position during the return movement thereunder of the brush, after which the second toothed portion of the gear j by means of the continued rotation ofthe shaft 9 engages with the gear 7' and ope This is provided for in the case of-an oblong or other similar irregular shaped box by means of the cam and other coacting parts referred to-that is, as shown in the drawings, the cam is adapted to support the boxwith its long side in a certain plane, as shown in Fig. 1, and then at the proper predetermined time be given a partial or one-halt revolution to raise the plate band support the box with I same plane.

vided the vertical shaft is its end in the same plane as the preceding side In thismanner it will be understood that the several successivesides of the box may each be presented to the brush in the cam j in a transversely-adjustable position upon the shaft j, whereby its opposite platesupporting surfaces may be adjusted relative to the axis of the shaft-21, e., the cam the secured with its said opposite surfaces an equal distance from the axis of the shaft'for square boxes and with one side nearer to and the opposite side farther fr m said axis for boxes of different lengths. v

To provide'for the adjustment of the cam, I have provided the latter with an elongated slot toreceive the shaft, whereby it may be moved transversely relative to the latter, as

shownin Fig. 17, and have secured it in ad- 3' usted position in connection with a fixed collarj on the shaft by means of an adjustingscrew 7' on the cam engaging with the said fixed collar j as shown in Figs. 16, 17, and 18. Two pins or screws ff connect with the collar 7' and extend through two elongated slots-j y in the cam, so as to serve in holding the latter from turningrelative toits said sup- '9 porting-collar. p

Simultaneously with the raising or lowering of the box-holder by the action of the cam j after the brush has moved back from beneath the box, as described, the box is given a quar-fjroo ter-turnforthe purpose of presenting the next side of the box to the action of thebrushu Such turning of the box. may be secured by an y suitable means, the means as herein illus-.

trated being asibllows: The box-holder shaft c, which is journaledin the blockb is provided with a bevel-gear k at its rear end, which meshes with a bevel-gear 70', located on a vertically-arranged shaft k r This shaft 10 .which is journaled in suitable bearingsih the i re frame,.-is provided with a second bevel-gear it adjacent to its lower end, which meshes with a gear 70, located in the end of a herizontally-arranged shaft '75, which latteris ,driven from the intermittently-rotating shaft and it, as v j through the mediumof gears 7 more'clearly shown in Fig. 3. To secure the proper timing in the relative movements-of the parts-that is, to turn the box simultaneously as it is being raised or lowered to hold zo such newly-turned side in'the same plane as the preceding side-the teeth in the segmental ear k are so arran ed as to mesh or en a e with the gear k and give the box a quarterturn onlyduring such time as the shaft j is 1215 being operated to continue or completethe half-revolution of the cam j, which takes place after the latter has received its preliminary.

movement for the purpose of elevating the box during the return movementot' the brush. r 0

' To provide for the vertical movement of'tlie box-holder shaftc with the block b in its connections with the lower shaftlo with-a longitudi In order to provide for boxes'of difierent dimensions, I have supported the I have promil slot k therein, through which a pin ex tends from the gear so as to allow the shaft to have a vertical movement independent of the box-hold or stationary afterit has received" said gear, and have journaled. the upper end i of the shaft in a fixed arm Months block b which arm engages with thelower edge of the hub of the gear is andsupports the shaft, in

vertical position, with the said gear 70 in mesh with thegear 7c.

A's asimple means for assisting in holding f its quarter-turn and while the brush" is ap ed a spring-pressed pin Z in the block b which is normally held with one end extending into plying the strip to its under side I have se-' cured a disk 1, having four notches Z in. its periphery, upon the shaft 0 and have support one of the said notches Z in the disk'l, as

clearly shown in Fig. 1. v ated fromthe shaft j to withdraw from the notch in the. disk 1 at the time the box-holder .is given its preliminary vertical movement bruslrbcneath the box.

25 shaft m in bracket-arms m m of the supportpreparatory to-the return movement of the This operation -is secured by mounting a vertically-arranged in'gkframe and providing the same with a rigidly-connected arm m adjacent to its upper end, which extends in front of a projection m on the pin Z, (see Fig. 2,) and vwith asecond arm mi adjacent .to its lower end, which engages with a cam m on the shaft j, as more clearly shown in Figs. 2'and 3. The forward pressure of the spring-pressed pin against theengagingarm m of the shaft m holds the lower ar-m' m on the latter with a yielding I pressure against the cam m5. Thus when the shaft j receives its first'partial revolution to give the box-holder its preliminary verticah movement, as described,-the cam m on said shaft is thereby operated to act upon the engaging arm m of the shaft mend operate the latter to cause its upper arm m to move the pin 1 out of the notch in the disk Z, wherebythe latter is free to be turned. After the box-holder has been operated to receive its quarter-turn the cam W has also been turned to a position to permit the pin Z to be pressed forward. into the next notch in the disk Z, which has-been brought opposite the same.

' In some'instances, as when setting or ad justing the machine, it maybe desirable to turn the box-holder independent of its auto-.

matic'operating mechanism. To allow for this, I provide the shaft m with a second lower arm m, which is connected with the .fixed arm m' of a tr'e'adle-shaft m through the either sidebeyoud the edges of the latter after being applied thereto by the action of the This pin Z is oper- "roams brush. According to my present invention these loose projecting. sides of the strip are turned around the edges of the'box and ap: plied to the adjacent surfaces of thelatter byautomatically-operating means, the means as herein illustrated being asfollows: The'brush- ."carriage d, which consists of a substantially square open frame or casting,as clearly shown in Figs. 2 and 7, is provided with two rods 02 n,

carried thereby, which extend in a direction lengthwise of the machine, on'each of which,

at a pointin the rear of the brush, is pivotally supported a seriesof strip engaging and applying devices, which consist in the present instance shown of elbow-levers, (represented at 0 and 19, respectively.) The vertical arms of these lovers are preferablyformed of spring-wire and are each provided with a roll adjacent to their end, which rolls are arranged at varying angles relative to each other and adapted during-the forward movement of the carriage to successively engage with the loose projecting sides or edges of the covering-strip and properly bend and apply the same to the adjacent surfacesof the box, as shown in Fig. 6 The rolls 0 on the several levers 0..are adapted to engage with that edge (denoted at l'i n Fig. 5;) of the coyeging-strip which is to be applied to the bottom of the box, and therefore-are arranged with the first roll, or the one.

nearestthe box, extending in a substantially horizontal position, so as to readily pass beneath the projecting edge of the coveringstrip, while the following rolls are arranged at a substantially uniform variation of angle between said first roll and the last one, which latteris arranged in a substantially vertical position, as shown. By this construction it will be understood that as the carriage d, is moved forward to cary the brush beneath the box and apply the covering-strip thereto the several rolls 0 will successively engage with the projecting edge of the strip and gradually bend the same around the corner of the box and against the bottom of the latter, the last one or two' rolls operating to press the said edges-closely against the box. g As a means to insure the edge of the covering-strip being held against the edges of the box and in position to receive the first of the rolls 0 thereunder, as shown in Fig. 5, Ihave supported a block 0 on the'carriage immediately in front of the said rolls, the forward; and inner sides of which are tapered back-' ward and outwardly, respectively, so/a's to raise and hold the edge of the strip in position to insure the roll passing thereunder. At a point forward of this said block 0 I have also provided the carriage with an arm q, having a roll q, supported thereby in a position to engageiwith the projecting edge 2 of the covering-strip on the vertical side of the box and at the lbwer corner thereof and press the same against the bottom of the box, asshown in Fig; 5 This operation, preceding the application of the loose edge of the strip against the box by the rolls 0, insures the proper f0ld-' fing of thestrip where itovei'laps at the corners on the under side of the has.

The loweror horizontal arms of the leveroi are each provided with an antifriction-roller 0 adjacent totheir end, which .rest during the forward movement of the carriage and:

until the lovers are brought to a position opposite the box upon a cam or bed plate r;

This plate serves to'hold the levers in a position so that the rolls 0 may readily pass the forward corner of the box, and as the levers obvious, however, that thelever-arms which a carry the rolls 0 might be stationary upon the carriage and perform their function of bending and applying the loose edge of the strip upon the box. w

The springs o which throw the lever for-" ward after passing beyond the plate 1', areconnected at one end with the levers at o and at their opposite end connect with a fixed rodo, which'is supported upon the carriage.

Any undue forward movement of the-levers under the action'of said springs after passing from'the plate r is limited by astop-bar 0 against which a shoulder 0 on the lovers strikes.

The rolls p on the second oropposite series of levers p are adapted to engage with that edge of the covering-strip atthe top or open .side of the box and turn the same into and against the inner wall of the latter. To accomplish this, the several rolls are supported at varying angles, so that when brought to a position past the vertical edge of the box and opposite the inside of the latter they will successively engage with the loose edge of the'covering-strip and turn thesame into and against the inner wall of the box, it being understood that the rollers 3 on the le vers resting upon the plate 1' serve to hold .the rollstp in a position to permit them to pass the corner of the box, and as said rollers 10 move oi? the end of'the plate thereby allow the levers to be rocked under. the action of the springs p to IKNH'Q the pressing-rolls p forward into engagement with-the edge of the covering-strip. The last two or three of the rolls p bear upon the inner wall of the box with more or less pressure in pressing the turned-in edge of the covering-strip thereto, and as a support to the wall of thebo-x under such-pressure I have supported two rolls n n upon a plate it? im mediate] y-beneath the said upper pressing-rolls, which are carried beneath the-under side of the box as'asupport to the latter tinder thefpressure of the said upper rollspgas clearly shown in'hlig. 6. The

first of the series of levers p is formed so. that the aud o of its upper arm will be moved forr gward against the inner wall of'the box after its lower arm'has been moved from "engagethe rolls p is desirable, for the reason that when the covering'strip is applied to the outer surface of the side of the box the glue or paste on the covering-strip dampens such side, and therefore would cause the same, particularlyifformed of thin board, to bend or curl up at its outer or open edge if some provision, such as above described, was. not made to prevent the same. b

In order to provide for boxes of'diiferent widths, the rod n, on which the levers p are" pivotally supported, is connected with the plate n which is laterally adjustable in the frame don two cross-rods n n. This construction permits the levers pbeing adjusted relative to the levers 0 according to the depth of the box to bexcovered. The block 12 having its forward and inner sides tapered backward and on twardly, respective] y, for c odperatingwith the opposite block 0 in raising and supporting the covering-strip and the rod 19 for the support of'the upper end of the springs p are also connected with the plate 92 to be movable therewith.

As the rolls on the upper arms of the levers o and p successively reach a position at the opposite end of the box during the forward movement of the carriage, the rollers on the lowel' arm of the levers engage with the taporing end of a second cam-plate r and are moved upward upon the latter, and. thereby throw the rolls 0 and p backward and out of engagement with the box, so as to permit them to pass the end of the latter and also the projecting edges of the covering-strip.

- r The cam-plates 1' and r are each supported to slide in horizontally-arranged grooves r 1 in the supporting-frame a, as more clearly shown in Figs. 3 and 4. It will be understood that these plates must be located with their inner, or adjacent ends in a certain defi nite position relativeto the ends of the box in order to properly regulate the rocking movements of the elbow-lovers o and n into and from engagement with the box, as described, and for this reason it is desirable that the plates should be automatically adjusted to conform to the difiference in the length of the sides and ends of the box as they are successively presented to the brush and rolls and also to the dilferent sizes of boxes. I secure such automatic adjustment inthe present instance shown as follows: A

double rack r is connected with the vertically-movable plate I) and meshes with two oppositely-located segmental gears r and '27-, which are journaled in fixed bracket-arms of the supporting-frame, as more-clearly shown in. Fi g. 2. These gears 1- and 7' are each connected with the plates 1' and 0", respectively,

through the medium of two levers r and '1,

' which are pivotally supported upon fixed arms of the frame a, with their inner or ad-. jacent ends having a slot-and-pin connection and with the outer end of the lever 2 having a link connection with the lower end of the gears at r and the outer end of the lever r having a-linlt'connection with the center of the cam-plates at r, as shown. By this con= struction it will be understood that as the plate I) is either raised or lowered with the box-holder for the purpose of supporting either the end or side of the box in the path of the brush, as before'described, the connected rack r will also' be moved therewith to operate the engaging gears, and thereby move the connected plates r and r either toward or away from each other, according to the length of the box side to be presented for the application of the covering-strip. For instance, after the long side of the box has had the strip applied thereto, as shown in Fig. 1, the plate I) is then raised a certain distance to support the end of the box when turned in a the same plane as that in which the preceding long side of the box was supported, and such raising of the plate b causes cam-"plates r and r to he moved toward each other a suificient distance so that their adjacent ends will coincide with the ends of that side of thebox just presented. At'the'next turn. of the box when the block b is lowered the said cam-platesfiwill thenhe moved apart, &c In setting these platesr andr' for a certain. size of box the box is first placed on theboxholder, which is properly adjusted to receive the same, and the rack 1'3, which- ,bas a slid' ing dovetailed connection with the plate I), as shown, is then moved either up or down on the latter to bring the connected plates in their proper position relativeto the ends of the box, after which it'is secured in fixed ad'- justed position'on the plate by means of a set-screw r When the covering-strip is being applied to the box and before it is caused to adhere to each side thereof by the brush, its edges have a tendency to sag andcurl by reason of the strip being dampened byjthe adhesive material thereon, and inorder to prevent such undue sagging, whereby the brush may spread the strip smoothly upon the box, I

has been located fore described, the turned-in edges of the strip at the four inside corners ofthe box re: quire a further pressing inorder to cause them to closely-fit into the box-corners and give the box that finished appearance which is desirable, it being understood that the rolls p when operating on the inside edge of the "-box do not closely conform to the corners of the latter. Such further pressing and fitting of the edges of the strip in the corners of the box may be done by hand, if desired; but it is preferable that the same should be don'e on the machine, and to accomplish this I havesupported a rod 'v in the hollow box-holder shaft 0, with its front end projectingforwar-d through'the latter 'andj'having a cross-rod oattached thereto." 'The opposite ends of this cross-rod connect withtwo bars r n by extending through central-openings therein,

which bars connect at their ends with four sliding blocks '0 which'are supportedlon the arms c'iof the box-holder, as clearly shown in Figs. 3,. 9, 10, and 11.- By this construction it will be understood that the rod '0 may be pushedforward in'the shaft a and .m'ove'the connected blocks '0 longitudinally onthe arms 0 andintothe corne'rs'of'the box,'so as to closely press. the turned-in edges of; the

strip against the same. The forward corners vtof "the blocks (u? are slightly tapered, a's shown, so'as'topermit their,.ready entrance intothe' box aud also allow them to engage with the edges of thestrip without tearing the same. The entrance of the blocks ni -into the'box is further-permitted by meansfof the blocks '0 ,on the ends of the arms .0 which en-- gage with the box to support the same, with a1 space between its inner wall and thesaid arms.

The bars c n connect with-the block's 'v 'by extending loosely. through openings therein, and such connection, together with the loose sliding connection-between the said. bars and the cross-rod v, permits the varied adjustments of the box-holder arms 0 as hereinbefore idescribed,w-ithout interfering therewith. The rod 12 may be operated to move the blocks o by hand orany other suitable means, the same as=herein shown being adapted to be operated by a foot-treadle w through the me-' dium of connecting-means, which latter, as herei-n'shown, consists 'of a-vertically-arranged shaft to, which is supported inbracket arms 0 w of the supporting-frame and provided with a fixed parallel arm to adjacent to its upper end, which extends between two fixed disks wtufi on the rod o, and with a second fixed arm 20 adjacent to its lower end,

which is connected with the fixedarm 'w of 0, with the connected blocks o forward.

Upon removingthepressure from the said treadle a connected spring 20 elevates the yieldingly held'in engagement with same,and thereby operates theseveral: parts to withdraw the blocks from their position within the box. Du ring thebperation of the machine and 5 after the 1 eovering-strip has been partially. applied to the boxth'esaid strip is' a'ad-apted to be cut ata desired point t'o give theproper len'gth'of strip for covering the box; Such severing of the'strip maybe securedfby. any to suitable means,the means ashereinfshown con sisting of a cutter devices, which comprises a stationary blade s'anda pivoted-blade-s ,both of said blades being carried by abracket-arm sfiwhich is supported to slide on one of the rods I5 which carry the strip-guiding arms a". V The pivoted blade 5 is connected at its rear end' 'with a' link .9 which has a horizontal sliding connection at its lower end with a shaft 8 which latten is loosely supported in two slotzoeted" swinging arms 8 8 attached to the 'supporting-frame. A vertically-disposed rod 8 is connected at its upper' end with the said cross'shaft s and is provided with a pin or projection s? in one side thereof, which is antiperating cam-disk t ona shaft t by meansof a coiled s ringsfiwhich bears'at one end against a colla' s on said shaft and at its opposite. 7 end against a fixed arm s ot the supportingframe. The said shaft t, which carries the cam i, is driven from the shaft 9 through the medium of gears t and 6 as more clearly shown in Fig. 15, 'and'is so timed thatthe projection t of the cam z" is caused to engage with the pin 5 on the rod 8 'so as to raise the latter and ope-rate the cutter once during every'complete revolution of the box-holder. The rods is connected at its lower end with a foot-lever s whereby it may he raised to 40 operate the cutter independent of its automatic operating mechanism. In order to adjust thecutter for severing the strip in different lengths according to the size of the box.to be covered, the bracket-arm s, which supports the cutter, is shifted longitudinally upon its supporting-rod, and the lower end of the con nec'ting-links s is also correspond- -ingly shifted on the shaft 8 Such construction permits the cutter to be readily adjusted 5o withoutinterfering with the rods and its connecting operating, parts.

The clutch mechanism for automatically stoppingthe machine after-the box has been covered consists of an ordinary crab-clutch u,

supported on the d riving-sbaftof the machine and having connection with a pivoted elbow-' lever u",.by means of which the operator may move the clutch into position to render the machine operative,:an l also having connec 60, tion with a second elbow-lever u which latter is pivotally supported on the frame at M, with the end of its lower arm connected with ,a vertically-arranged rod a which isp'rovided with a pin '21? on 'one side thereof'for engagen1ent with a cam a on the shaft-t. A coiled spring Won the rod t bears at one end '1 against a fixed arm a of the supporting- :frame and at its opposite endbears against a "as shown clearly in Fig. 16, reaches a position opposite the said pin-the latter is forced by causes the elbow-lever a to rock and move therein by the act-ion of the spring, and'therethelclutch from engagement with itsconnectingpart, and so stop the machine.
